    摘要： A utility cart (10) for hauling up to at least 1000 pounds includes a plastic carriage (11) having reinforcement ribs (47) extending from and across the bottom thereof to strengthen the carriage (11), an elongated drawbar member (12) to pull the carriage (11), an axle assembly (15) engaging the carriage (11) and one end of the drawbar member (12) to pivot the carriage (11) with respect to the drawbar member (12), a latch assembly (16) connected to the drawbar member (12) and engaging the carriage (11) to restrain the pivotal movement of the carriage (11) with respect to the drawbar member (12), and at least two wheels (13, 14) attached to the axle assembly (15). The latch assembly (16) includes a body member (53) pivotally connected to the drawbar member (12) and has a gripping portion (56) extending between a first leg portion (57) and a second leg portion (58). A rod (54) attached to the carriage (11) is received by slots (67) in the leg portions (57, 58) to releasably engage the carriage (11) to the drawbar member (12).
